This invention relates to an improved method of and improved means for making booklets of cigarette paper.

Booklets of cigarette paper are usually in the form of a stack of individual sheets of gummed or plain cigarette paper of uniform dimension and enclosed in a cover of thick paper stock, the ends of the cover overlapping one another. Usually, the cover bears advertising indicia such as a trade-mark, pertaining to either the cigarette paper per se or to a particular brand or. brands of tobacco which may be suitable as the filler for the cigarettes, the paper serving as the outer container tube.

Usually, the advertising or other printed matter appearing on the cover is arranged within printed outlines, the edges of the cover at the open ends of the thus formed booklet being preferably severed in symmetrically spaced relation to such marginal lines.

Heretofore, such booklets of cigarette paper.

have been made by practically wholly manual operations, the individual paper sheets being manually stacked and cut and placed within individual book covers.

An object of the present invention is to climb nate as far as practicable the manual operations involved.

A feature of the invention is the provision of a plurality of strips of indefinite length of cigarette paper; preferably corresponding to the number of individual sheets to be contained in a single booklet, assembling the strips in substantially superposed relationship and severing the super- A preferred form of my invention embodiesv suitable procedure and means for feeding the cover strip in proper relation to the superposed strips of cigarette paper, folding over the end portions of the strip to enclose the strips of cigarette paper and severing the thus combined cover strip enclosing the superposed strips of cigarette paper in the proper lines of severing to locate the printed marginal lines and/or the printed mattar as an entirety in desired relationship to the edges of the resulting individual booklets of cigarette paper.

Pursuant to the preferred forms of my invention, the respective strips of cigarette paper are located'at'or before the stage of severing under 5 conditions of substantially uniform tension, whereby upon severing of the superimposed strips, the resulting individual sheets are of substantially uniform dimension.

My invention contemplates suitable procedure 10 and means whereby adjustment is aflorded between the severing means, usually a knife of the guillotine type, and the cover strip and enclosedsuperposed strips of cigarette paper, to compensate for relative displacement, including varial5 tions arising from change of temperature, humidity, difference in character of paper stock, etc.

An object of my invention is an improved machine for arranging strips of paper of indeter- 20 minate length in superimposed relation to each other and with such strips of paper either gummed or ungummed, as desired, and the enclosing of such superimposed strips of paperin a wrapping means which forms the wrapper of 25 l larly where such plurality of sheets after beingso superimposed upon each other are enclosed within a wrapper, there is a considerable amount of air trapped not only within the wrapper,-but also between adjacent strips of paper. It is essential in order to produce uniform books from 35 the strips of indeterminate length, that the paper as a unit be fed without serious distortion, and this is impossible where a pair of cooperating rolls are utilized as a means for acting on the superimposed strips of paper to feed the same 40 to the cutting device. The entrapped air tends to force the strips of paper out of registry with each other and actually to cause a lateral flattening out and distortion of the enwrapped. paper.

An object of myinvention therefore is an improved meansfor so feeding the enwrapped plurality of superimposed st'ripsof paper as to avoid any series of derangement thereof or distortion of the shape of the package or resulting book of cig- 6 arette paper. g Further features and objects of the invention will be more fully understood from the followingdetail dacriptionandthe drawings in which Fig. 1 is a side elevation showing a. machine embodying my invention;

Referring to the drawings, l0 designates a framework built up of angular iron, or of castings bolted together as may be preferred, and such framework at the lower ends of the uprights thereof is provided with bases all preferably lying in the same horizontal plane and. the framework i0 is supported by a base l2, such as a concrete base, or by anyv other rigid support.

The framework I0 is composed of parallel sides, as the sides 13 and I4 shown in Fig. 10 connected together by various cross members, such as the cross member I5. At one end of the framework IO, and at what may be called the entrance end of such framework, and in each of the side members l3 and I4 are bearings in alignment with each other and in which bearings is mounted a shaft l6.

On the shaft l 6 is pivotally arranged a plurality of elongated strips or plates ll of the character shown in Fig 5, such strips being of rel- -atively thin metal and each of such plates has securely fastened thereto by riveting, or in any other suitable manner, a laterally extending stub shaft I8, and on each shaft is rotatably mounted a roller l9. The plates H are equally spaced apart from each other by collars 20, loosely mounted on the shaft l6, see Fig. 4.

At the extreme end of the side frame members I3 and I4 and below the shaft I6 are laterally extending arms 2|, and secured to such arms and lying parallel to the shaft I6 is a shaft 22, such shaft being provided with a plurality of parallelly arranged grooves 23 of approximately the width of the thickness of the plates I1, and the space between such grooves 23 is approximately the distance between the plates H, as defined by the collars 29 on the shaft l6. The plates II are therefore not only rotatably or pivotally mounted on the shaft IE, but the lower ends thereof are housed in the slots or grooves 23. To insure the plates I! being held in the desired position with respect to the shaft I6 and shaft 22, I arrange at the end of each of the 5 arms 2|, a groove 24 in which is adapted to be placed a. bar 25, preferably of wood, although :ny other material may be employed for such The bar 25 acts as a locking means to prevent 10 unauthorized outward movement of the various plates I! from the grooves 23. Fitting on each .of the rotatable rollers I9 is a roll 26 of cigarette paper which has been preferably, although not necessarily, specially prepared to have a line of 15 adhesive material extending along the length thereof and adjacent to one edge and on one I face thereof, it being understood that when the strips 26 are arranged parallel to or superimposed on each other, that the adhesive edges will also 20 be booked in like manner, that is, superimposed one on the other.

On the side frame members l3 and H and relatively adjacent to the shaft l6 are downwardly extending arms 21 in which are formed bearings 25 to receive an idler shaft 28 which is arranged parallel to the shaft l6 and therefore to the axes of the rolls of cigarette paper26. The cigarette paper 26 passes from the rolls and under the idler ,roll 28, as clearly shown in Figs. 1 and 3. Adja- 30 cent to the idler roll 28 and in the side frame members l3 and H are arranged bearings in which is rotatably mounted a roller 29 and over which the strips of cigarette paper 26 are fed, as clearly shown in Fig. 3. Secured to one end of 35 the roller 29 is a bevel gear 30 which meshes with and is driven by a similar bevel gear 3|, secured to one end of a shaft 32, such shaft being rotatably mounted in bearings 33 on the side frame member l3. On the end of the shaft 32 remote 4 from the bevel gear 3| is secured a. sprocket '34 which is in alignment with a sprocket pinion 35 secured to one end of a shaft .36 that isrotatably mounted in aligned bearings 31 on the side frame member l3 and adjacent to the top edge thereof. 5

I Over the aligned sprockets 34 and 35 runs a sprocket chain 38 and by means of which power is transmitted from the shaft 36 to the shaft 32 and thence to the roller 29.v On the end of the shaft 36 remote from the sprocket pinion 35 is 50 a sprocket 39 which is in alignment with a sprocket 40 secured to a shaft 4| rotatably mounted in bearings 42 in the framework I0. Over the sprockets 39 and 49 runs a sprocket chain 43, by means of which power is transmitted 55 from the shaft 4| to the shaft 36 and thence to the roller 29 in the manner above described.

On the shaft 4| adjacent to the sprocket 40 is a sprocket 44, which is in alignment with a sprocket 45 secured to a countershaft 46 rotat- 0 ably mounted in bearings 41 on the side frame member l3 and over the sprockets 44 and 45 runs a sprocket chain 48 and by means of which power is transmitted from the countershaft 46 to the shaft 4|. 0n the countershaft 46 is 65 mounted a loose pulley 49 and-a tight pulley 50,

.these pulleys being in alignment with a wide to the countershaft 46 and thence to the mechanism above described, or not, as desired.

n the end of the jack shaft 52, remote from the wide pulley is arranged a gear 55 which meshes with and is driven by a pinion 56 on the drive shaft 51 of the motor 54a, such motor being securely mounted on the concrete or other base l2. In the side frame members I8 and I4 and adjacent to the bearings of the roller 28 are arranged guideways 58, (see Figs. 2 and 3) in which are slidably mounted bearing members 59, and in such bearing members is rotatably mounted a shaft 68, such shaft being enlarged in its intermediate portion, as indicated by the reference numeral 6i, and on the enlarged portion is arranged a tubular member 62 of relatively resilient material, such as rubber or the like.

The bearings 59 are yieldingly held in the guideways 58 by the springs 68, and means such as the bolts 84 are utilized to force the shaft 68 and therefore the resilient cover 62 of the member 6I'into relatively close association with the surface of the roller 29. On the end of the roller 29 remote from the bevel gear 88 is arranged a gear 65 which meshes with and drives a gear 86 secured on the adjacent .end of the shaft 68. The roller 29, and therefore the roller 62, are driven in opposite directions and at the same peripheral speed and the strips 26 of cigarette paper are fed between such rolls and downward as clearly shown in Figs. 1 and 3.

It is desirable at this point in the travel of the strips 26 of cigarette paper to provide a relatively large bight therein to facilitate subsequent operations thereon and I have therefore arranged in the concrete or other base I2 a suitable well 61 (see Fig. 1) in which such bight of the strips 26 are housed, and to insure the bight remaining in position, I have provided each bight of each strip 26 of cigarette paper with a ring or other formation of wire 68. From the ring 68 the strips 26 of cigarette paper pass upwardly of the machine until the top of such machine is reached, the strips of paper 26 which, as they pass through the rolls 29 and 62, lie parallel to each other and in substantially the same horizontal plane, and as they pass to the top of the framework I8, they are still parallel to each other, but lie in a plurality of superimposed planes, and as thus position, pass between a pair of spaced guide plates 69, as clearly shown in Fig. 10.

In the path of movement of the upwardly extending portion of thebights of cigarette paper strips 26 and on the framework I8 are arranged spaced bars I8, which act as a means for initially forcing or crowding the individual strips 26 into superimposed position with respect to each other. On the framework I8 above the bars I8 is ar-- ranged a mechanism for completing the operation of superimposing the strips 26 of cigarette paper with respect to each other, and such mechanism comprises mechanism that is illustrated in Fig. 1, and more clearly shown in enlarged form in Figs. 7, 8 and 9.

Such superimposing mechanism is relatively independent of the feeding mechanism for both the strips 26 of cigarette paper and the covering means therefor, and is therefore operated by a motor II mounted on a pedestal'12, formed integral with or separate from the framework I8. The drive shaft of the motor II has secured to one end thereof a sprocket pinion 18 which is in alignment with a. sprocket wheel I4, secured to a shaft 15 that is rotatably mounted in suitable bearings formed'in the framework I8 and over the sprocket pinion I8 and sprocket wheel I4 runs a sprocket chain 16 and which drives the shaft I5 at the appropriate speed and in. the direction of the arrow shown in F18. '7.

On the shaft I5 adjacent to the sprocket wheel 5 I4 is a sprocket 11 which is in alignment with a sprocket 18 secured to a shaft I9 mounted for rotation in the framework I8 and parallel to but spaced apart from the shaft I5, as clearly shown in Fig. 7. Over the aligned sprockets I1 and I8 runs a sprocket chain 88 and which rotates the shaft I9 at the proper speed and in the direction of the arrow shown in Fig. 7.

Above the shaft and in the framework I8 is rotatably mounted a 'shaft' 8I parallel to both the 15 shaft 15 and the shaft I9. Also in the framework I8 and parallel to the shafts 8|, I5 and I9, respectively, but spaced apart therefrom and on the opposite side of the plurality of strips 26 of cigarette paper are the shafts 82, 88 and 84, and 20 on the shafts I9, 8|, 82, 88' and 84 are secured the sprockets 65, 86, 81, 88 and 89, respectively, such sprockets being equal in pitch and diameter and all in alignment with'each other and over such sprockets runs the endless sprocket chain 98. By reference to Fig. '7, it will be noted that the shafts 19, 8|, 82 and 84 rotate in the same direction, but because of the position of the sprocket chain 98 on the sprocket 88, the shaft 88 rotates in the opposite direction, as indicated by the arrow in Fig. 7. Also, it will be understood that these shafts rotate at the same speed.

Extending between the side frame members I8 and I4 and in alignment with the shafts I9 and 84 is a shaft 9| which may be of any shape, but preferably square, and on such shaft are slidably mounted members 92 and 98, respectively, one such member being located on either side of the plurality of strips 26 of cigarette paper, and each of these brackets 92 and 98 has extending out- 40 wardly therefrom or rearwardly or to the left, as viewed in Fig. 1, arms 94 and 95, respectively, such arms 94 and 95 being spaced apart from each other a distance considerably greater than the width of the strips 26 of cigarette paper, and such distance is maintained by means of a plate 91 extending between the members 92 and 98 and secured thereto by screws 98. Pivotally mounted to the member 93 is one end of a connecting rod 99, and the other end of this connecting rod is pivotally mounted on a crank pin I 88, eccentrically arranged on the shaft 84. Rotation of the shaft 84 will therefore cause a reciprocating motion of the arms 94 and 95, so as to bring them alternately into engagement with the edges of the strips 26 of cigarette paper it is desired to super impose on each other.

Secured to the side frame members I3 and I4 and in alignment with the shafts I5 and- 83, is a non-circular and preferably square shaft IM and on this shaft are slidably mounted the members I 82 and I88, respectively, such members being provided with outwardly or rearwardly extending arms I84 and I85, respectively, sucharms being similar to the arms 94 and 95, but not necessarily of such length as such arms. The distance between the arms I84 and I85 is greater than the width of a strip 26 of cigarette paper, but such distance is less than the distance between the arms 94 and 95, and similarly to such arms 94 and 95, the distance between the arms I84 and I85 is maintained by the plate I86 secured to the members I82 and I88 by the screws I81.

Pivotally mounted to the member I88 is one end of a connecting rod I88, and the other end of this connecting rod is pivotally attached to a crank pin I09 eccentrically arranged on the shaft 83.

By referring to Fig. '7, it will be obvious that when the arm on the member 93 is in engagement with the edges of the plurality of strips 26 of cigarette paper it is desired to superimpose on each other, that the arm I04 on the opposite side of the strip 26 of cigarette paper will be in engagement with the opposite edges of the plurality of strips 26 of cigarette paper, andthe same is true with regard to the arms 94 and I05.

Secured to the side frame members I3 and I4 and in alignment with the shafts BI and 82 is a non-circular and preferably square bar IIIO, on which are slidabiy mounted the members II I and 2.. These members III and H2 are provided with outwardly or rearwardly extending arms I I 3 and I I4, respectively, such arms being of suitable length but not necessarily of the length of either of the arms I04 and I05 or 94 and 95.

Pivotally mounted on the member II I is one end of a connecting rod I I 5, the other end of this connecting rod being pivotally mounted on a crank pin I I6 eccentrically arranged on the shaft 8 I. Pivotally mounted on the member I I2 is one end of a connecting rod I I1 and the other end of this connecting rod is pivofally mounted on a crank pin Ilp eccentrically mounted on the shaft 82.

The distance between the arms H3 and H4 at any time is less than the distance between the arms I 04 and I05 or between the arms SM and 95, and the connection of the driving means therefore on the shafts SI and 82 is such that the arms I I3 and I I 4 approach each other simultaneously and separate from each other simultaneously.

On the side frame member I4, below the shaft 84, is rotatably mounted a shaft II9, such, shaft being parallel to the shaft 84 and provided adjacent one end with a sprocket wheel I20. This sprocket wheel I20 is in alignment with a sprocket wheel I2I on the shaft 84 and over these sprocket wheels runs a sprocket chain I22 and by means of which power is transmitted from the shaft 84 to the shaft I I8.

Mounted on the end of the shaft II9 adjacent to sprocket wheel I20 is a bevel pinion I25 which meshes with and drives a bevel gear I26, secured to a shaft I21 rotatably mounted in bearings I28 and I29, and such shaft I21 lies at right angles to the shaft H9 and extends inwardly toward the side frame member I3. Such shaft, however, terminates approximately midway between the side frame members I3 and I4 and on its inner end has secured thereto a face plate I30.

Eccentrically mounted on the face plate I30 and extending laterally outward therefrom is a crank pin I3I and to which is pivotally attached one end of a connecting rod I32. The other end of this connecting rod is pivotally attached to the forked end of amember I33. The member I33 has formed integral therewith a plate I34, which plate is provided with a plurality of parallelly arranged slots I35, the number of such slots I35 being equal to the number of strips 26 of cigarette paper, and one strip 26 is fed through each of the slots I35.

The approximate size of the strips 26 of cigarette paper with respect to the slots I35 is clearly apparent from an inspection of Fig. 9.

At the end of the plate I34, remote from the member I33, is a pair of spaced ears or lugs I36, andto such ears by means of a pin I31 is pivotaily attached one end of a link I38.

The upper end of the link I38 is pivotally mounted on a shaft I39 mounted in the spaced arms or brackets I40 formed integral with the framework I0 (see Fig. 1).

As the strips 26 of cigarette paper move upward 5 from the bight above referred to, such strips are crowded together slightly by the arms 10 and are then passed up through the slots I35 in the plate I34, but it will be obvious that due to the length of the slots I35 as compared with the width of 10 the strips 26 of cigarette paper that such strips 26 are not yet at this stage superimposed one on the other. The strips 26 are therefore led up from the plate I34 between the arms 94, 95, the arms I04, I05, and the arms H3 and H4, and 15 thence through the spaced guide plates 69. After passing through the space guide 69, mechanism to be hereinafter described, carries the now superimposed strips 26 onward through the machine, but prior thereto, the motor H is started 20 in operation and through the chain of sprockets and sprocket wheels, above described, reciprocatory motion is imparted to the plate I34 and from the connections I 32 and I38 it is obvious that a. relatively compound or complex motion is im- 25 parted to the plate I34, and this complex motion is imparted to the strips 26 of cigarette paper tending to shake out any curve or twist that may tend to be put into the strips 26 so that the strips pass upward from the plate I34 parallel to each 30 other, but not definitely superimposed on each other.

As the strips 26 pass upward through the pair of arms 94, 95, the edges of the strips 26 are alternately struck by the arms 94 and 95 tending 3:! thus to bring the strips 26 more and more into superimposed position. Any advantage gained by the arms 94 and 95 in this direction is enhanced by the arms I04 and I05 which in turn are operated to strike alternately the opposite edges 40 of the strips 26 and as above described, the space between the arms I04 and I05 is less than the distance between the arms 94 and 95.

After passing upward from the arms I04 and I05, the parallelly arranged strips 26 which are 45 at this time brought nearer into superimposed position have the edges thereof engaged simultaneously by the arms I I3 and II 4, which arms complete the final act of bringing the strips 26 of cigarette paper into superimposed position, so 50 that as the strips 26 pass through the guide plates 69, they are accurately superimposed on each other.

Formed on the side frame members I3 and I4 are aligned upwardly extending brackets, but 55 one of which, the bracket I 42 on the side frame member I3, being shown in Fig. 1. At the upper end of the brackets are U-shaped openings or bearings I43 in which is rotatably mounted a removable shaft I44. Rotatably mounted on the 0 shaft I44 is a roll of cigarette paper book cover material I45, and such material is fed from the roll downward under the roller I46 and over a roller I 41, which roller I41 is provided with an outer sleeve or covering I48 of relatively resilient 5 material, as for example rubber or the like.

The rollers I46 and I41 (see Figs. 1 and 6) have their ends machined in the usual manner and such ends are rotatably mounted in suitable bearings formed in the side frame members I3 70 and I4. On one of the rollers, the roller I46, is secured a bevel gear I49, which meshes with and is driven by a corresponding bevel gear I50 secured to one end of a shaft I5I, such shaft I5I being rotatably mounted in aligned bearings 75 I52, secured to or formed integral with the side frame member I3. Secured to the end of the shaft I5I remote from the bevel gear I56 Is a sprocket wheel I53, which is in alignment with a sprocket wheel I54 secured to the shaft 32 and over'the sprockets I53 and I54 runs a sprocket chain I55, and by means of which power is transmitted from the shaft 32 to the shaft I5I, and thus in turn to the roller I46. The roller I41 is driven by suitable gearing between such roller and the roller I46 in the same manner as the roller 6I is driven from the roller 29, as above described.

After passing from the roller I41, the covering material I45 passes downward in a loop or bieht within the well 61 and over a roller aligned bearings in the side frame members I3 and I4, and then moves what may be termed rearwardly of the machine or to the left of Fig. 1, and around a roller I51, which is rotatably mounted in suitable bearings in the side frame members I3 and I4 and the roller I51 is of such a diameter as to bring the covering material I45 into a horizontal plane that lies substantially.

in the horizontal plane in which the superimposed strips 26 of cigarette paper lie as they.

pass through the guide plates 69.

The roller I51 is flanged as indicated at I58 (see Fig. 10) so that the cover material I45 is centrally located with respect to and beneath the superimposed strips 26 of cigarette material. The cover material I45 and the strips 26 of cigarette paper are thus brought into association with each other and travel onward through the machine or to the right as shown in Fig. 10, at the same speed, so that there is no relative motion between these two materials.

On the framework I6 and in the path of movement of the associated materials I45 and 26 lies a guide I59 which acts to partially fold the cover material I45 about the groups of superimposed strips 26 of cigarette paper, as will be clearly apparent in Fig. 10. After passing through the guide I59, the partially folded cover material I45 on one fold thereof comes into engagement with a rotatably mounted member I66 which acts to fold one portion of the overlapping edges of the cover material I45 under the other. The now practically enclosed superimposed strips 26 of cigarette paper pass from the member I66 and into a guide member I6I, where the operation of folding the cover material I45 about the superimposed strips 26 of cigarette paper is completely performed.

The enclosed strips 26 now pass through a mechanism which feeds the same onward and cuts the same off into books of appropriate length, such feeding and cutting mechanism comprising the following instrumentalities.

Adjacent the end of the framework I6 and extending inwardly from the side frame members I3 and I4 are aligned pairs of bearings I6I, I 62, andI63, I64, respectively. In the pair of bear- Ings I6I, I62 is fixedly mounted a shaft I65, while in the pair of bearings I63, I64 is fixedly mounted a shaft 166. These shafts lie parallel to each other and extend lengthwise of the framework 1 I0. slidably mounted on the shafts I65 and I66 is a relatively elongated framework composed of :'spaced end members I61 and I68. The members I 61 and I68 are connected together by integrally formed spaced bars and thence upwardly I56 rotatably mounted in a cross member I16 and such cross member I16 hasformed integral therewith and extending laterally outward from one side thereof a boss "I that is internally threaded to receive the threaded screw member I12. 6 Secured to the screw member I12 (see Figs. 10 and 14) is a worm wheel I13, and secured to the extreme end of the screw member-I12 is a collar I14. The screw member I12 is rotatably mounted in a bearing I15 formed in a bracket 10 member I16 on the side frame member I4. The worm wheel I13 mesheswith and is driven by a worm I11 secured to a shaft I18 rotatably mounted in bearings I19 and I86 formed in the side frame members I3 and I 4, respectively. 15

' 11 and 14) joined together by the members I 69 25 along the parallelly arranged spaced shafts I65 and I66, and this ability to move the above named construction permits of an adjustment for a purpose in a manner to be hereinafter described.

In the lower end of the pair of spaced end 30 members I61, and extending transversely of the framework I6 is a shaft I83 (see Fig. 11). In the same relative position with respect to the pair of members I68 is rotatably mounted a shaft I84. Mounted on shafts I83 and I84 are sprocket 35 wheels I85 and I86, respectively, the sprocket wheels I85 and I 86 being of the same pitch and diameter and over such sprocket wheels, which are in alignment with each other, runs a sprocket chain I81. The sprocket chain I81 has aflixed thereto and extending transversely thereof, at proper spaced intervals, bars I88. The upper reach of the sprocket chain I81 with the transverse bars I88 thereon lies in a horizontal plane and in a plane coincident with the horizontal 5 plane in which lie the strips 26 of cigarette paper enclosed in the wrapping material I45, so that the upper reach of the sprocket chain I81 forms practically a platen on which the cigarette paper may rest or is fed. 5

In each of the pairs of end members I61 and I68, vertically above the shaft I83, are vertical guideways I 89 and I96, respectively, and in the pairs of guideways I 89 and I96, respectively, are slidably mounted pairs of bearings I 9I and I 92, 55 respectively, each pair of bearings I8I and I92, respectively, being yieldingly held in the guideways I89 and I96, respectively, by the helical springs I93 and I94, respectively. The top of the pairs of guideways I89 and I96, respectively, are no closed by plates I and I96, respectively, and extending through such plates are set screws I91 and I98, respectively, to thereby adjustably position the bearings I9I and I92, respectively, in their guideways. I 65 Rotatably mounted in the pair of bearings I9I is the shaft I99, while rotatably mounted in the bearing I92 is the shaft 266. These shafts are parallel to each other and to the shafts I83 and pitch and diameter to each other and to the 75 sprockets I and I86, and over such sprocket runs a sprocket chain 203. The sprocket chain 203 has securedthereto along its length transversely arranged bars 204, these bars being similar in all respects to the bars I88 on the sprocket chain I81 and the spacing also of such bars 204 is identical with the spacing of the bars I88.

Also, the lower reach of the sprocket chain 203 lies parallel to the upper reach of the sprocket chain I81, and the bars I88 and 204, as the sprocket chains I81 and 203 move onwardly, are in registry with each other and the lower reach of the sprocket chain 203 with the cross bars 204 thereon lies in a plane parallel to the plane in which lies the upper reach of the sprocket chain I81 with the cross bars I80 thereon, and the distance between such planes is slightly less than the thickness of the plurality of superimposed sheets 26 of cigarette paper plus the thicknesses of the folded covering material I and such-distance may be varied'as desired in the following manner.

Beneath the upper reach of the endless sprocket chain I81 and engaging the under surface of the cross bars I88 and at each end of such cross bars are vertical tracks 205. Along the lower inner edge of each of the tracks 205 is arranged and angle iron 206, and secured to the angle irons and therefore to the tracks 205, adjacent each end of the angle irons 206 is a cross bar 201, such cross bars being attached to the angle irons 206 and therefore to the vertical spaced tracks 205. The ends of the cross bar 201 extend laterally outwardly beyond the tracks 205 and such cross bars have secured thereto at each end thereof upwardly extending bolts 208, the upper ends of such bolts being threaded to receive nuts 209.

Resting on the upper face of the cross bars 204 of the lower'reach of the endless sprocket chain 203 are spaced tracks 2I0 similar to the tracks.

205, and secured to the upper inner edge of each of the tracks 2I0 is an angle iron 2I I. Secured to the angle irons 2I I, adjacent to the ends thereof and vertically above the cross bars 201, as above described, are cross bars 2I2, such cross bars being drilled to allow free passage of the threaded bolts 208.

Surrounding the upper part of the threaded bolts 208, and lying between the nuts 209 and the upper surface of the cross bars 2I2, are helical springs 2 I3, and the tension of the springs may be regulated by the nuts 209 in the usual manner, thus tending to yieldingly hold the tracks 2I0 and tracks 205 in engagement with the cross bars 204 of the sprocket chain 203 and the under surface of the cross bars I88: of the sprocket chain I81 between which, as will be noted, is situated the strips 26 of cigarette paper enclosed in the outer wrapping I45.

The distance between successive cross bars I88 and between successive cross bars 204 is approximately equal to-the length of a so-called book of cigarette papers, but this is merely for convenience and the distance between such cross bars may be anything that is desired, the object to be attained being to grasp the superimposed strips 26 of cigarette paper enveloped in the outer wrapping material I45 at a. plurality of spaced points along its length to thereby feed the same through the machine rather than to have such enclosed plurality of superimposed strips 26 of cigarette paper fed through by feed rolls or equivalent, which will at all times be in engagement with the paper at the point of feed.

therefrom.

This is essential as it has been found that the use of a roller feed tends to roll up a portion of the material backof the exit end and distorts and renders unsalable the cigarette paper booked Secured to the shaft 4I adjacent the inner-, most of the bearings 42 is a worm 2I4 which meshes with and drives a worm wheel 2I5, secured to a shaft 2I6 rotatably mounted in bearings 2| 1 formed at the lower end of the member I10. Secured to one end of the shaft 2I6 is a face plate'2l8 that is provided with a diametrically arranged T-slot 2I9, and in which slot is adjustably mounted the crank pin 220. Pivotally mounted on the crank pin 220 is one end of a connecting rod MI and the other end of this connecting rod is pivotally attached to one end of a lever 222, which lever is rotatably mounted on the shaft I84. Secured to the shaft I84 adjacent to the lever 222 is a ratchet wheel 223 and with the teeth of such ratchet wheel engages the spring pressed pawl 224 that is pivotally mounted on the lever 222 at the end thereof remote from the connection of the connecting rod 22I.

It is obvious, therefore, that rotary movement of the shaft 2I6 by reason of power transmitted thereto from the motor 54a will result in an oscillatory motion of the lever 222 and therefore in an intermittent step by step rotary movement of the shaft I84, this in turn resulting in an intermittent step by step movement of the lower and upper reaches of the spring chains 203 and I81, respectively. Also, this will necessarily result in an intermittent step by step motion of the plurality of strips 26 of cigarette paper enclosed in the outer wrapping material I45.

The shaft 4| is rotated through suitable mechanism from the motor 54a as above described, but may be rotated independently thereof by means of a. hand wheel 225 secured to the end of the shaft 4I, adjacent to the position naturally occupied by the operator of the machine.

Adjacent to the outermost bearing 42 of the shaft H is a cam plate 226, provided on one face with a cam groove 221, and in which works a cam roller 228. This cam roller 229,is secured to a cross bearing 229, as clearly shown in Fig. 13. Secured to and extending upwardly from the cross bar 229, while arranged parallel to and spaced apart from each other, are shafts or rods 230, such rods or shafts passing upward through suitable vertical bearings in the framework I0. At the upper end of the shafts or rods 230 is arranged a cross head 23I, carrying on its lower edge a guillotine knife 232, which extends transversely of the path of travel of the superimposed strips 26 of cigarette paper.

The guillotine knife 232 operates in association with a fixed blade or anvil 233. As the shaft 4I rotates, such rotary motion is imparted to the cam plate 226, and the roller 228, riding in the cam groove 221, imparts to the cross bar or cross head 229 a reciprocating movement in a vertical plane. Thus, through the medium of the shafts or rods 230, and cross head 23I, a reciprocating movement in a vertical plane, is imparted to the guillotine knife 232. The construction and arrangement of the cam groove 221 and the cam plate 226 with respect to the comstruction and arrangement of the intermittent drive for the sprocket chains I81 and 203-is"such that the downward movement of the guillotine knife 232 into association with the anvil or fixed blade 233 takes place during pause or stop of such chains I81 and 203, is a guideplate 234 and a sight 235. The outer covering material I45 for the plurality of superimposed strips 25 of cigarette paper is ordinarily provided with indicia such as printed or other advertising matter to denote the origin and character of the goods enclosed therein, and such indicia or a particular portion thereof on the space between said indicia or a particular portion thereof may be utilized as a guide along which to sever the books of cigarette paper from the indeterminate length of enclosed cigarette paper by means of the relative position of the sight 235 with respect to the guillotine knife 232. It may be that because of weather conditions, such as will affect the physical characteristics of the paper, either of the outer covering I45 and/or the strips 26 of cigarette paper; that the feed of the enclosed cigarette paper, as determined by the intermittent step by step movement of the sprocket chains I81 and 203, will result in gradually disturbing the relative arrangement in the cut necessary to sever a book from the indeterminate length of papers, and. at the proper place to position the indicia thereon properly with respect to the book to be severed.

To correct any distortion resulting from this cause, the operator by turning the hand wheel I8! in the proper direction can and will move the entire assembly constituting the sprocket chains feed I81 and 203 either toward or from the guillotine knife 232, and such distortion may be accurately measured by picking out the appropriate element of the indicia on the outer wrapping I45.

In Fig. 12, the letter R on the word LEAD- ER" is shown in the proper position to permit the guillotine knife 232 to sever a book of cigarette papers from the indeterminate length of such cigarette papers and presumably the next succeeding cut made by the guillotine knife 232 may be on the dot and dash line 236 that is visible at the right hand end of sight 235.

The intermittent step by step feed of the endless sprocket chains I81 and 203 is such as to cause an, onward movement of the indeterminate lengthsrof covering and cigarette paper 23 in steps equal to the length of the books to be cut therefrom, and such length of feed may be accurately determined bymeans of the T-slot M9 and the crank pin 220, the T-slot and crank pin 220 making it possible 'to adjust the length of the stroke or feed of the endless sprocket chains I81 and 203 within any length required or desired within the limits of the machine.

Assuming the machine to have been constructed and assembled as above described and that it is desired to operate the same, thelopera tor will place on the rollers I9 the reels or rolls of cigarette paper 26, the number of rolls 25 .the same in position. The operator .will then take the ends of the strip 26 of cigarette paper and bring the same under the roll 28 and between the rolls 29 and 6 I, thence downwardly into bights or loops in the well 61, weighting each bight o'r loop with a ring 68 and then bring each of the ends of the strips 26 upward between the spaced arms I0 and then threadeach end of the strips 26 through the slots I35 in the plate I34,.thus bringing the same into substantially parallelism with each other; The strips are then fed up through the pairs of arms 94, 05, I04, I05, and H3 and I I4, and thence upward between the spaced plates 69, the distance between such plates, as above described,v being substantially equal to the width of the strips 26 of cigarette i p The strips 26, as they pass between the plates 60, are now in registry with eachother and in superposed position and are brought forward onto the now upper surface of the covering material I45. With the strips I26 in position on the covering material I45, such covering material and therefore the strips 26 are fed through the preliminary folding device I59, where the outer covering material is given a preliminary folding about the superimposed strips 26. From the device I59 the now partially'enclosed strips 26 are moved along and one side of the outer covering material I45 is brought into engagement with the member I60 which turns down such edge into position beneath the other or opposite 30 edge. The now substantially enclosed cigarette paper 26 is brought through the folding device IBI where the strips 26 of cigarette paper are completely enclosed in the outer covering material I45 and such material is now fed through and between the endless sprocket chains I81 and 203, such sprocket chains being operated for this purpose by the hand wheel 225;

The material after coming out through the exit end of the sprocket chains I81 and 203 is 40 fed through the sight member 235 and the guides 234 until the proper element of the indicia on the outer covering material I is in proper registry with the sight 235. l

To properly position such element of the in- 45 dicia, the operator manipulates the hand wheel I 8| to move the entire feeding mechanism to-' ward or from the knife 232 as may be required. The machine having been properly set up, the operator will throw power into the motor 'II to operate the pairs of arms 95 and 04, I04 and I05, and -I I3 and H4, and the plate 134.

The motor 54:; may be presumed to be in operation whereupon the operator will move the belt 54 from the loose pulley ,40 over to the tight 5 pulley 50, thus throwing power into the power transmitting mechanism, above described in detail, and the machine is in operation. 1

Theoperation is continued as'long as any paper remains on the reels, and shouldbreakage 0 of any individual strip 26"occur, the operator may temporarily shut down the machine and either remove the broken-reel of cigarette paper 26, or patch the same as may be'desired.

Any form of book collecting device may be used andpreferably I utilize a form'which is indicated in Fig. 1 by the reference numeral 250, and wherein the pile-up of cigarette paper books is held in substantially elevated position above the line of travel of the latest book out from the indeterminate length of book material and which latest book when'positioned over the pile is added thereto by appropriate mechanism, as for example, mechanism driven from the-cross-head to which is attached the lowerends of-the reof the resiliency of the outer covering material While the form indicated'and above briefly described is the preferred form, it is obvious that any other form of book collecting device may be utilized and I do not, therefore, limit myself to any particular type of book collector.

In Fig. 10, I have described the roller I60 which is utilized as a means for folding over one edge of the length of the covering material I46 to place such edge under the opposite edge, but I may and preferably do utilize alsoon the opposite side of the stream of covering cigarette paper a pair of idler rolls "I which will sufliciently guide the said opposite edge of the strip I45 so as to positively guide the same into association with the folding mechanism ISI.

By' referring to Fig. 10, it will be noted that the so-called opposite edge, that is the edge opposite to that engaged by the roller I60, does not fiow into, the folding and guiding member IBI, as such edge flows on the outside of such member IIiI, as indicated, thereby allowing a closer folding of the edges of the covering material I45.

7 Further, and referring to Fig. 9, there is shown the comb member I34, provided with the plurality of parallelly arranged grooves or slots I35,

'and such comb member I34 is closed, that is,

' I both sides are closed and the slots I35 are rectangular slots extending vertically-as viewed in Fig. '9--therethrough. This showing, however, is for convenience only and Imay and preferably do have one or theother of the lateral edges I of such comb member I34 open so that the slots or grooves I35 in such case become actual slots and the comb I34 more nearly an actual comb.

This construction is of advantage in that it facilitates the weaving of the strips 28 of cigarette paper into the comb and also facilitates the repair or replacement of any strip upon breaking of one or more of the strips 26.

" While I have necessarily described and illushated the preferred embodiment of my invention somewhat in detail, it is to be understood that I may vary the size, shape and arrangement of parts comprising the device-within relatively wide limits without departing from the spirit v cutting device arranged on the base and in the line of travel of the superimposed strips of material; and a feeding device for feeding such superimposed strips of material to the cutting means and movable as a unit with respect to the cutting device.
